Structural Chemistry and the Local Charge Picture of Copper Oxide Superconductors

R. J. Cava 1

1 AT&T Bell Laboratories, Murray Hill, NJ 07974

The crystal structures of the known copper oxide superconductors are described, with particular emphasis on the manner in which they fall into structural families. The local charge picture, a framework for understanding the influence of chemical composition, stoichiometry, and doping on the electrical properties of complex structures, is also described.
